No, its an operation system.
But many GUIs have been written to run on unix.
Unix is not a graphical user interface (GUI). It is an operating system that originally did not have a graphic interface and still does not have a GUI interface as part of the system. The standard user interface in UNIX is a command line as in a terminal session, similar to a windows command line interface.
Various graphic user interfaces are available for the unix and linux platform. Nearly all are based on the X Windows System (or X or X11 for version 11). X is a system for describing via API (program calls) and tables all the parts of a GUI including window attributes, position, boundaries, menus, mouse/pointer and input support. Nearly all unix/linux implementations as well as some other systems use X to create the windowing environment from the simple TWM (Tab Windows Manager) to DecWindows, Motif, CDE (Common Desktop Environment), to Gnome, KDE, xfc, and many more.
It wasn't just a GUI environment for a computer. It was a client/server environment that allowed remote control of a machine from elsewhere on a network or the internet. The commands to start the windowing environment on your machine also allowed you to specify that all the graphic display output generated on your machine from your session (the client) should be sent to another machine running an X windows Server.
It in UNIX the GUI is separate from the operating system itself. You can uninstall the GUI and still have a completely working UNIX system.

Graphical User Interface - in other words, the on screen commands that you interact with.
Many Unix and Linux servers come without a graphical user interface, and the text mode interface is the default. For those systems using a GUI, there is a 'terminal' tool that you can select from the menu to allow text interactions.
Yes, Unix has several variants of Graphical User Interfaces that may be used instead of the command line if the user wishes it.

Very true - the X-windows graphical interface was not available in Unix systems for a long time after Unix was available.

Several different versions of UNIX have GUI's or Graphical User Interfaces. The most common example of UNIX with an interface is Mac OS X.

Apple did not invent the graphical user interface. Xerox invented and commercialized it in 1973. Apple created the first successful computer with a graphical user interface.
A computer's graphical user interface can be controlled with a mouse or trackpad.
